Description

The technical field to which the invention relates

The present invention relates to railway technology.

Technical problem

When distributing and / or dosing heavy media (known under the abbreviation CHFC, from Composite Heavy Fluid Compound) with a high content of solid abrasive particles, sliding and moving parts of the ejection distribution and / or dosing element can be damaged very quickly. This leads to high maintenance costs and production interruptions. Therefore, the technical problem is to provide a pushing distribution and / or dispensing element that does not have sliding and / or moving parts or has a limited number of said sliding and / or moving parts, essentially exposed to the action of a medium, preferably CHFC, or a plurality of such media.

State of the art

Distribution elements are known from the prior art, the principle of operation of which is based on the fact that the distributed medium, which is usually a lubricant, but can also be another liquid, often an abrasive one, passes through the said distribution element and at the same time is in contact with him. Since such ejector dispensing and / or dispensing elements are precisely assembled, contents with abrasive solids in a very short time cause excessive play or sticking of the ejector element.

Disclosure of the essence of the invention

The flexible ejection dispensing and / or metering element solves the above technical problem by using a flexible insert having different functions during the expulsion of the CHFC and during the pumping of the specified CHFC from the reservoir in which it is contained.

An ejection dispensing and / or metering element for a medium, in particular a multicomponent mixture of heavy media (CHFC), or a plurality of such media is characterized in that it comprises an ejection means, preferably an ejector pin, movable between a first position, preferably a lower one, in which said flexible insert is maximally deformed and has the smallest internal volume, and a second position, preferably the upper one, in which said flexible insert is minimally deformed and has the largest internal volume, while said flexible insert, which remains substantially undeformed during pumping of said medium, preferably CHFC, from its reservoir, which is preferably located outside of said flexible ejection distribution and / or dispensing element, into a compression space, which is essentially a through hole formed in said flexible insert and delimited with one st orons, preferably with an upper, said ejection means, preferably an ejector pin, and on the other hand, preferably with a lower, non-return valve, wherein said pumping (pushing out) is carried out by moving said ejector means, preferably an ejector pin, from said second position to said the first position, wherein said flexible insert abuts against the body of the pushing distribution and / or metering element around its perimeter, said pushing distribution and / or metering element is deformed during pushing out by said pushing means, preferably by a pushing pin acting on the upper flange of the pushing distribution and / or a metering element so that the through hole is narrowed, and due to the decrease in the internal volume, a predetermined amount of medium, preferably CHFC, is expelled through said check valve.

The medium according to the present invention can be selected from the group consisting of a multicomponent mixture of heavy liquids, a lubricant and a material for increasing friction.

The flexible insert according to the present invention can be connected on one side, preferably to the top, to the flange, preferably to the top flange, and on the other side to the flange, preferably to the bottom flange, in order to maintain a substantially uniform deformation of said flexible insert.

The ejection dispensing and / or dispensing element may comprise a check valve to prevent the medium, preferably the CHFC, from returning to the compression space.

A method for dispensing and / or dispensing a medium, preferably CHFC, using a push-out dispensing and / or dispensing element comprises the following steps:

lifting of the ejection means, preferably a pusher pin, away from the flexible insert, which, due to the resulting vacuum, meaning a pressure lower than the pressure in said reservoir, pumps the medium, preferably CHFC, from the reservoir, preferably from the external reservoir, into the compression space, which is essentially a through hole in the flexible insert, said through hole bounded on one side, preferably on the upper side, by a pushing means, preferably a push pin, and on the other side, preferably on the bottom, by a check valve;

pushing the ejection means, preferably the ejector pin, towards the flexible insert, which, due to the increased pressure generated, deforms the said flexible insert, reducing the volume of the compression space, and as a result pushes the specified medium, preferably CHFC, through the check valve from the ejection distribution and / or metering element.
